VALVE- To all whom it mag concern: q Be it known thatLJoHN F. KEENAN, a OltlZGIlrOf the United States, and resident of Providence, in the coimty of Providence and State of Rhode Island, havednvented:

certain new and: useful Improvements in;

. Valves, at which thefollowing isavspecification.

i This invention relates to improvements in the construction ofhdischarge valves for flushing tanks, and.the object of this invention is; first, topr ovide such a valve 1 through thebottomthereof and settingu a l nut beneath;'second, to so formtheva ve structure that when mounted. in the tank it sets so nearly flush with. the bottom thereof 3 t that each time the tank isemPtied all of the sediment will pass out and not be permitted to accumulateto soil thebowl. g

:A further 'object of the invention is to position the overflow discharge opening entirely within the periphery of the body of the discharge-tube of the valve structure so as to obviate the necessity of further cuttingaway the bottom of the tank for the reception of the overflow discharge opening.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the ap ended claim.

n the accompanying drawlngs Figure 1 is a sectional elevation of the flushing tank, showing my improved valve structure mounted therein.

Fig. 2 is an enlarged sectional side elevation of the body portion of the valve structure, showing the same as applled to the bottom of a tank, which latter is shown in dotted lines.

Fig. 3- is a top view of the valve struc ture.

Fig. 4 is a sectional view of the valve structure on line H of Fig. 2.

Referring to the drawings, 10 designates the flush tank proper which is used in connection with water closets and the like, which tank may be constructed of any suitable material such as porcelain, cast iron, or metal-lined wood, but whatever its construction it is found in practice very desirable that the opening through the bottom of the tank shall be circular and of a standard size, so that when a correspondingly sized valve 1.

structure is placed therein it may bereadily drawn tightly by an-outside binding nut to prevent-leakage- To accomplish this :ina simple and effective way, I have provided a valve structure or seat portion which has a tubularmember ll'circularin shape and vadapted to extend through the bottom of the tank 12 from the inside outwardly and is-provided on its inner edge with avery thin annularflange 13 underwhich is placed athin packing washer 14 .tolset against the inner surface of the bottom of the tank. I J a One'of the features of this construction is that the overflow discharge opening-.15 is formed within the outer periphery of the body member 11, the overflow pipe 16 being connected to. an offset portion 17 leading by way ofthe channel-.18. to the discharge openingl5.

-In order to provide aseat 20 for the valve 19. which I controls the main flushing discharge through this bodyiaportionprl"have offset the center of this seat from the center of the body portion andsohave provided both a maln flushing opening and an overflow discharge openlng within the diameter of the tubular body member 11, and yet the water passing through this main discharge has a direct fall through the conducting pipe 21 below, which is of importance in order to produce the maximum flushing effect.

The outer surface of this tubular body 11 is threaded as at 21 and when positioned to extend through the bottom 12 of the tank, a nut 22 is screwed beneath it for the purpose of drawing the flange 13 down tightly against its packing on the inner surface of the tank forming an absolutely tight joint and that by the use of standard fittings.

It is found in practice that where the flange 13 is made so very thin that it is diiiicult to hold the body member from rotating while the nut 23 is being screwed up to bind the whole in position. Therefore to facilitate the holding of this member during the screwing action on the nut, I have provided an upwardly extending boss 24: on the upper surface of the flange 13 which serves as a fulcrum for one end of a lever 25, shown in dotted lines in Fig. 3, whereby the whole valve structure may be firmly held in position during the setting up of the nut.

Then again this boss is found to be conven ient to receive a refilling passage 28 which is tapped at 26 for the reception of the threaded end of the refilling pipe 27, through which'pipe a predetermine amount of water is permitted to pass for the pur- 5 pose of refilling the bowl after having been My improved valve seat member is extremely practical in construction and may be positioned in the tank with the expenditure of but the minimum amount of time and when positioned will be absolutely tight.

Among other advantages in this structure are first,that the flange is made so very thin that practically all of the Water in the tank is forced out at each flushing operation thereby preventing the accumulation of sediment to discolor the bowl. Another advantage of this thin flange is that when the water is drawn off from the plumbing syssame, but just sufficient moisture remains in the tank to preserve the effectiveness of the packings.

Then again by my improved construction the overflow outlet leads to a point below the valve seat wholly within the outer circumference of the outer portion of the valve seat structure thus eliminating the necessity of cutting away any portion of the tank proper in order thatthe samemay be positioned therein.

tem to prevent freezing there is not suflicient left in this tank to freeze and damage the The device is extremely simple and prac tical in construction and effective in its operation and by its use a new valve seat structure may be positioned with great ease and with the minimum expense.

The v foregoing description is directed solely toward the construction illustrated, but I desire'it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claim. Y

I claim: 1

In a flushing tank, a valve structure having a circularytubular body adapted to ex tend through the bottom of the tank, said body having a thin annular flange. seated against the inner surface of the bottom of the tank, said body being provided with an overflow discharge opening located entirely with in its circular body; avalve seat formed within said body offset from the center thereof,

. and an upwardly projecting leverage lug on said flange located at a point substantially .oppositethe overflow inlet, said lug being provided with a channel through it leading into the discharge pipe. at a point below the valve seat, said channel being adapted to receive an after-fill tube in its upper end.

In testimonywhereof I a'flix my signature.
